HOOK-AND-EYE SAFETY-LOCK.

Application filed October 2, 1919.

To all whom t may concern:

Be it known that I, LEWIS PETER BoUR Gnors, J r., a citizen of the United States, residing at Gramercy, in the Parish of St. James and State of Louisiana, have invented certain new and useful Improvements in Hook-and-Eye Safety-Locks; and I do hereby declare the following to b e a full, clear, and exact description of the invention, such as will enable othershskilled in the art to which it appertains to make and use the same.

The present invention relates to improvements in hook and eye safety locks, and has for an object to provide an improved device for holding the hook in the eye until such device is released to permit disengagement of the hook.

It is a further obj ect of the present invention to provide a device for the above described purpose which will be simple and cheap in construction, capable of being readily applied where desired, and easy in operation.

In the accompanying drawings forming a part of this application, and in which similar reference symbols indicate corresponding parts in the several views:

Figure 1 is a perspective view of an improved hook and eye safety lock constructed in accordance with the present invention and shown applied to a door shown in fragmentary section.

Fig. 2 is a fragmentary elevational view of the improved device shown as applied to the door shown in section and broken away; and

Fig. 3 is a plan view of the improved device.

Referring more particularly to the drawings, 1 designates a door adapted to close in a door jamb 2, and 3 represents a hook having an eye 4 at its opposite end mounted in a screw eye 5 which is carried by the door jamb 2. The hook 3 is adapted to engage through an eye 6 carried by the door l so that when the door is in closed position, the

'hook 3 may be made to pass through the eye 6 whereby the door may be held fast.

In practice it has been found that the hook 3 is apt to escape from the eye 6 and permit opening of the door 1 when not desired, and by use of the present invention this accidental unfastening of the hook is avoided.

The invention employs a plate 7 prefer- Speccaton of Letters Patent.

ably of the elongated rectangular construction shown, and provided with perforations to receive the upper screw 8 and the screw eye 6 whereby such plate 7 may be secured to the door l. The plate carries a staple 9 in which the downwardly turned perforatedA ears 10 of a lever l1 are fulcrumed, and above the staple 9 the end of the lever is turned up as indicated at 12 to provide an operating piece adapted to be pressed down against the plate 7 whereby the opposite end of the lever l1 may be lifted away from the eye 6, as shown in dotted lines in Fig. 2.

The lever 11 is narrowed at its intermediate portion from which the ears 10 are stamped and bent over, and the same flares outwardly toward its lower end where it is centrally provided with a lug 13 which is bent upwardly and curved to conform substantially to the curvature of the rounded portion of the hook 3 which it engages as shown in Figs. 1 and 2, and in this manner serves to hold the hook 3 in the eye 6 and prevents its escaping therefrom.

Horns 14 and 15 are formed in one piece with the lever l1 and cut and twisted from the lower end thereof, such horns being disposed to opposite sides of the lug 13 and acting to center the lug on the hook and prevent any lateral escape of the hook from the eye 6. These horns 14 and 15 project forwardly and outwardly, as is clear from Figs. 1 and 3. The horns 14 and 15 are severed along their rear side from the adjacent portions of the lever 11, and such adjacent portions are bent down to provide prongs 16 of substantially triangular construction adapted to rest against the plate 7 when the lever 11 is in the locking position. The prongs 16 are shown engaging the plates 7 in Fig. 2, and they act to hold the lever away from the platea suitable distance to permit the lug 13 and the horns 14 and 15 to have proper engagement with the hook 3.

In use, the parts are in the position shown in Figs. l and 2, in which case the hook 3 is i arrangement is such that the hook 3 may be engaged with and disengaged from the eye 6 by one hand while the operating piece l2 of the lever 11 is depressed by the other hand, so that the unhooking of the door 1 may be readily accomplished.

It is obvious that those skilled in the art may vary the details of construction and arrangements of parts without departing from the spirit of my invention, and therefore I do not wish to be limited to such features except as may be required by the claims.

I claim:

1. In combination with a hook and an eye, a lever having a lug struck up from one end and arranged to engage the hook when the lever is in one position to prevent its escape from the eye, said lever also having horns formed on the end thereof and at opposite sides of said lug, prongs also formed on the end of said lever for holding the lever with the lug engaged with the hook, and an operating piece on the other end of the lever whereby the lever may be rocked to withdraw the lug and horns from the hook, substantially as described.

2. A device of the character described including a hook, an eye, a plate having a perforation adapted t0 receive said eye, the eye assisting to hold the plate in place, a lever having perforated ears struck therefrom and fulcrumed on said plate, a turned up end on one end of the lever acting as an operating piece whereby the lever may be swung on said fulcrum, prongs bent from the other end of the lever and adapted to engage said plate, horns adjacent said prongs, and a curved lug between said horns and adapted to engage the hook and hold the same in the eye, substantially as described.'
